Factors that affect chemical injuries
What percent are children
Concentration Liberation Absorption Distribution Metabolism Excretion 60% are children
Anaphylaxis is most associated with
antibiotics (penicillin)
Asprin overdose
Kids: 2-4 grams
Adults: 10-30grams
Respiratory alkalosis followed by metabolic acidosis
Tylenol overose
15-20grams
liver failure over several hours to days
Lead exposure problems
High affinity for enzymes making hemoglobin
Microcytic hypochomic anemia
Allowable lead blood levels
5 ug/dL
Lead exposure for adults
peripheral neuropathies (wristdrop, footdrop)
Factors affecting thermal burns (5)
Percent of body removed (9s..50% is death) Depth Internal injuries Age How fast/well was it treated
Shock associated with 30-40 % burn
Hypovolemic shock
Skin changes after radiation
2-3 days: erythema
2-3 weeks: edema
4-6 weeks: blistering
Month-Yrs: Atrophy, Cancers
Cell changes after radiations
Hrs: lymphocytes
weeks-months:rebound
1-2 weeks: Granulocytes
2-3 months: Rebound
Fatal Acute radiation syndromes
Hematopoietic 2-10 sv, 2-6 weeks
GI: 10-20 sv, 1-2 weeks weeks
Cerebral: 50sv, 1-4 hrs
Lethal radiation range
2Sv
7Sv is certain death
Marasmus
What is it
How to tell
Deficiency in caloric intake
Somatic department depleted
Weight is less than 60% of normal
Indicator of immune system deficits
Thrush
Kwashiorkor
What is it
What does it look like
greater deficiency of protein than total calories
Visceral department depleted leading to decreased albumen leading to edema
Flaky paint looking skin
Less than 5 years old
Functions of Vitamin A
Maintain vision in reduced light
Differentiation of mucus epithelial cells
Immunity esp. in children
Functions of Vitamin C (3)
Formation/stabilization of collagen (hydroxylate proline and lysine)
Convert tyrosine to catecholamines
Antioxidant
